Deis Workflow v2
Deis (pronounced DAY-iss) is an open source PaaS that makes it easy to deploy and manage applications on your own servers. Deis builds on Kubernetes to provide a lightweight, Heroku-inspired workflow.
Work in Progress
Deis Workflow v2 is changing quickly. Your feedback and participation are more than welcome, but be aware that this project is considered a work in progress.
Hacking Workflow
First, install deis/etcd as described in its documentation. Ensure that the deis-etcd-service is running and healthy by accessing its port 4001 and seeing that the environment variable DEIS_ETCD_1_SERVICE_HOST is set.
One way to test this by running commands from another pod in the same namespace:
$ kubectl exec alpine -- env | grep DEIS_ETCD_1_SERVICE | sort
DEIS_ETCD_1_SERVICE_HOST=10.247.187.217
DEIS_ETCD_1_SERVICE_PORT=2380
DEIS_ETCD_1_SERVICE_PORT_CLIENT=4100
DEIS_ETCD_1_SERVICE_PORT_PEER=2380
$ kubectl exec alpine -- curl -sS 10.247.187.217:4100/version
{"etcdserver":"2.2.1","etcdcluster":"2.2.0"}
Next build the deis/workflow image and push it to a Docker registry. The $DEV_REGISTRY environment variable must point to a registry accessible to your Kubernetes cluster. You may need to configure the Docker engines on your Kubernetes nodes to allow --insecure-registry 192.168.0.0/16 (or the appropriate address range).
$ make docker-build docker-push
Finally create a PostgreSQL database and the Deis workflow service:
$ make kube-create-all
kubectl create -f manifests/deis-database-rc.yml
replicationcontrollers/deis-database
kubectl create -f manifests/deis-database-service.yml
services/deis-database
kubectl create -f manifests/deis-workflow-rc.yml.tmp
replicationcontrollers/deis-workflow
kubectl create -f manifests/deis-workflow-service.yml
services/deis-workflow
$ kubectl get pod
